ICE CREEPER.

Application filed January G, 1922. Serial No. 527.346.

To all Iwhom it may cancer-72 Be it known that l, Crime l. (x'rroiu), a citzen of the United States, residing at Eric, in the county of Eric and State of Pennsylvania, have invented certain new and useful Improvements in Ice Creepers; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying dravvings, and to the letters of reference marked thereon, forming part of this specfication.

My nvention relates to ice-creepers, and the object thereof is to provide a device by means of which suitable spurs or creepers can be secured under the heels or rubb-er overshoes Without the aid of screws or rivets, and which can be quickly placed on the overshoe or removed therefrom, as desired.

The features of my invention are hereinafter fully explained and pointed out and are illustrated in the accompanying drawings in Which:

Figure l, is a side elevation of a 'rubber over-shoe having an ce-creeperthereon embodying my invention.

Figure 2, is a plan view of the underside of the same.

Figure 3, is a section of the creeper Inechanism removed from the shoe, on the line m in Fig. 2.

Figure 4, is a front end view of my improved creeper mechanism.

Figure 5, is a plan view of a modified construction of my creeper mechanism.

In these drawings A indicates the sole portion of the heel of an over-shoe, Which, as is well known, projects in a sort of head around the heel. B is a middle plate provided with upturned ears Bf at opposite sides thereofa C indicates a wire secured in the upper ends of the ears 3 so that said wire will fit around the heel of the 'over-shoe and engage the upper edge of the sole A,

In Fig., 3 is illustrated the manner in which the ears B' are h-ent around the wire C, viZifrom the outside of the wire over and down and under, inside of the wire, so that the wire C is held in engagement with the bead of the heel sole A, around the entire perimeter of the heel of the over-shoe; F indicates a bar which is placed transverse of the over-shoe in front of the heel sole A, and the ends f thereof are upturned and hoolied, so as to receive the ends of the Wire C and hold the same inward against the body of the over-shoe and upon the heel sole To prevent bars F from moving forwardly, the ends o of the wire C are turned up-' wardly as shown in Fig. l and Fig Li. I also provide a strap G which is secured to the bar F and extends backwardly under the heel of the shoe and is secured to the plate B by means of a stud-pin g which extends through the hole g' in the strap G. Upon the under side of the plate B is secured a plate H, the edges H' of which are turned downwardly and at an angle to each other so that said edges form oleats which bite into the snow and ice. The plate H is formed therein and a guideway li through which the strap G sldably passes.

In Fig. 5 I show an alternative view in which the plate B is in two parts B2 and Bs, which are secured together by means of the spring Za; each of the parts 132 being provided with upturned ears B' as in Fig. l.

The plate H is permanently secured to one of the parts Bz, and the'other part 132 is provided with a slot Zi', in which slot a rivet bg operates to hold the part B2 upon the cleat plate H. The other features remain the same as in Figs. l and 2. The operation of the construction shown in Fig. 5 permits the parts Bg and. the ears B' thereon, to move inwardly when the ends c of the wire C are pressed toward each other in securing the creeper upon the over-shoe so that the upper beaded ends of the ears B' will be securely clamped upon the bead A of the heel sole of the over-shoe.

Having thus fully shown and described my invention so as to enable others to utuilize the same, l do not desire to be limited to the exact mechanism shown and described, as man? modifications can be made therein witlfout departing from the scope n"' vention; therefore what I claini as n f desire to secure by Letters Patent i? l. In device of the class descrbed, cleat plate, upwardly extendine ears on opposite edges thereof, a return-bend wire secured in said ears, a transverse bar engaging the free ends of said wire, rear'wardly extendng bar secured to the intermediate portion of said transverse bar, a guide-way plate secured on said cleat plate embracing said rearwardly extending bar, and means to adjust the length of said last mentioned bar between said transvers'e bar. v

2. In a device of the class descr'bcd,l a cleat plate, upWardly extendng ears ,on opposte edges thereof, a return-bend Wire secured in said ears, a transverse bar engagng'te free ends of said Wire, a rearwardly extendng bar having holes therethrough secured to the ntermedate porton of said transverse bar, means on said cleat plate to slidably'engage said rearwardly extendng bar, and a stud on said cleat plate adapted to engude-Way l plate and said 'Jr/Massa gage one of the holes in said rearwardly extendng bar.

3. In a device of the class descrbed, a cleat plate, a pair of plates laterally movable With relaton to each other and secured on said cleat plate, upturned ears on said last mentoned plates, a return-bend Wire secured in 'said ears, andmea'ns to clamp said Wire and ture.
